My cory got bitten on the tail and its getting worse not better?

They're naturally schooling fish. So he may just be not feeling comfortable because he is by himself.
I'm a bit stumped on his injuries. ...

I'm baffled too, none of the others have damaged mouths and I have had them for nearly a year! His entire 'nose' is gone :(

Any idea what type of meds I can give him? I'm doing a water change now and have just found another injured catfish, this one had a fairly large bruise or discoloration (possibly some sort of growth??) on the side of his 'neck'! I dont know if my Dwarf Neon Rainbowfish are still bullying them . . . I havent seen any . . .

Just an update, the other side of his tail (that was ok yesterday as shown in the picture) has now started to deteriorate. I think I'm going to have to start treating for fin rot - like right now.
Anyone know if the INTERPET brand "Anti fungus and finrot" treatment will be ok to use on him? I've heard of people using a half dose, will that be enough to cure him? I imagine I would have to treat him for longer than if I was using a full dose?

defiantely fin rot, im dealing with the same in my tank. his mouthn issue is a bac infection aswell. grab a bottle of mealfix its a api product and doesnt clolor or cloud your water. its a gentle medication made from tea trees or soemthing. "smells like vicks vapor rub" im on day 2 of my treatment and the fish are handleing it very well. i have a whole thread titled "fin rot" if you wanna take a peek. GL

But fin rot is from poor water quality? The OP states the water quality is par...

and so is my water, i woudl drink from my aquarium at anytime no questions asked. i bought the fish with the rot and they still have it a month later. the treatment is still in its second day for me but it could do no harm as melafix is super gentle and isnt effectign my fish at all. fin rot is from bacteria that is in EVERYONES aquarium, stress and nipped fins is what brings it out.

Sorry guys I'm not gettting messages when your posting!! Unfortunately I lost the poor little catfish yesterday. I picked up melafix on the way home from work on tuesday but when I got home he had already taken a turn for the worst, his tail was completly gone and the small fin on the bottom of his back had started to turn as well. I think he probably developed an infection from the original bite to his tail and it just spread throuh him, it was probably already to late when I moved him.

New problem, don't know if I can post photos from my phone but I will try, one of my other catfish has a strange lump/mark on his head/neck area. It seems to be agrivating him as he is hiting that side of his head on the gravel all the time! Any suggestions for this! It not red or bloody kindof a cream/peach color fairly large in comparison to his head. No other signs of disease or anyhing . . . . Should I quarentine him and start him on he melafix too?? Sorry for the spelling in this post, phone isn't great for typing!! Thanks all!!Posted via Mobile Device
